Release paper applied to medical indwelling needle sticker

Abstract

The invention discloses release paper applied to a medical indwelling needle sticker, and particularly relates to the field of release paper. The release paper comprises a release paper body, the release paper body is of a double-face release structure, one side of the release paper body is coated with a first silicone oil layer, and the other side, corresponding to the first silicone oil layer, of the release paper body is coated with a second silicone oil layer. Two heavy-release-force silicone oil formulas are blended and used on the first face and the second face of the paper respectively, corona treatment is conducted as an technology after silicone oil on the first face is cured, the release force and the surface energy of a heavy-face silicone oil layer are greatly improved, the adhesion strength of a PU film is changed by setting the corona value, and therefore the problem that PU cannot be attached to a heavy release surface is perfectly solved. Meanwhile, the second surface adopts a formula which is heavier than the light release force but lighter than the first surface in release force, so that the silicon transfer condition is avoided by adjusting the formula.

Description

technical field [0001] The invention relates to the field of release paper, in particular to a 120-gram double-sided silicon-coated glassine release paper that can be coated with medical polyurethane glue (PU glue). Release paper for medical indwelling needle stickers. Background technique [0002] Indwelling needle stickers are the second-class medical accessories produced by medical accessories companies. They are composed of two layers of release paper, one layer of pressure-sensitive adhesive, one layer of PU film and name stickers. [0003] In the production process of indwelling needle stickers, medical polyurethane glue (PU glue) is coated on the heavy release side of 120G release paper in a liquid state, but the traditional production process and technology of release paper cannot meet the requirements of polyurethane glue in the liquid state. Firm adhesion to the surface of the release paper, even if the release force is already very heavy, after the PU glue solidi...

Problems solved by technology

[0008] In order to overcome the above-mentioned defects of the prior art, the embodiment of the present invention provides a release paper applied to medical indwelling needle sticks, which are used on the first side and the second side of the paper respectively by formulating two kinds of heavy release silicone oil formulas. On the first side, after the silicone oil on the first side is cured, corona treatment is carried out on the process to greatly improve the release force and surface energy of the silicone oil layer on the heavy side. By setting the corona value, the adhesion of the PU film can be changed, so that It perfectly solves the problem that the heavy release surface cannot adhere to PU. At the same time, the second surface adopts a formula that is heavier than the light release force but lighter than the first surface. Through this formula adjustment, so that there is no silicon transfer
